Brigitte, Nyx's daughter (who, like her sisters and her mother, doesn't know about his father's true job), is kidnapped during a school trip by women smugglers that wants to sell her as a prostitute to her own father, who is currently working undercover. When Nyx finds out, he starts looking for her using his special abilities, a situation that alerts all the MI6's Roman division. In the meantime, Brigitte finds herself in company of Lupin and Jigen, who have casually stole the smugglers' car after a robbery.
